Coloured inks, paints absorb some wavelengths of light and reflecting or transmitting others. The three primary subtractive colours are yellow, magenta and cyan.
The yellow pigment absorbs blue light allowing red and green to pass through reflecting from its surface. We perceive the red and green light and see yellow.
The magenta pigment absorbs green light allowing red and blue to pass through or reflect from its surface. We perceive the red and blue light and see magenta.
The cyan pigment absorbs red light allowing green and blue light to pass through or reflect from its surface. We perceive the green and blue and see cyan.
Yellow ink absorb blue light, cyan ink absorbs red light. The only light that remains is green. Green is the subtractive secondary colour achieved by mixing two primary.
Yellow ink absorbs blue light, magenta ink absorbs green light. The only light that remains is red. Red is the subtractive secondary colour achieve by mixing two primary.
Magenta ink absorbs green light, cyan ink absorbs red light. The only light that remains is blue. Blue is the subtractive secondary colour achieved by mixing two primary.
When all three light are in the mix all three lights are absorbed (blue, green, red) therefore we cannot see any light in effect see black.
Yellow + Magenta + Cyan = Black
The printing industry use CMYK colour space, K representing not quite black = when all 3 subtractive colours are combined.

Light source from various wavelength is added in various proportion to produce a range of colours. Additive colour theory describes how we perceive color and how they are created. It is essentially colour created by mixing light of two or more different additive colours. The three primary additive colours are red, green and blue, otherwise referred to as RGB
Red & Green = yellow
Green & Blue = cyan
Red & Blue = magenta

Yellow, cyan and magenta are secondary additive colours. When all 3 primary colours and mixed it added together it creates white light. Computer monitors and television are most common examples of additive colours.

1. Contrast of saturation – this is the contrast between luminous and dull colours.
2. Contrast of light and dark – is the difference in brightness and tone values of colours, which can be lightened with white and darkened with black.
3. Contrast of extension – is based on the relative areas of two or more colours, such as large and small.
4. A complementary contrast – exist when two complementary colours are placed side by side.
5. Simultaneous contrast – is when the opposite colours are placed side by side creating the illusion of vibration or shadows.
6. Contrast of hue – is when pure colours are used in random combinations, which can be further enhanced with black and white.
7. Contrast of warm and cool – is created when warm colours (red, orange, yellow and brown) are place together to evoke a feeling or warmth and comfort. Alternatively cool colours (green, blue, gray) will educe feeling of sadness

Hue measured by degrees around the horizontal circle. Each horizontal circle is divided into 5 principal hues: Red, Yellow, Green, Blue and Purple along with 5 intermediate hues – which is halfway between each principal hues. There are now in effect 10 sub colours (red, yellow red, yellow, green yellow, green, blue green, blue, purple blue, purple, red purple). Within the 10 sub colours there are 5 hues = in total there are 100 hues separated in increments of 2.5.
Value measures the lightness; black (value 0) at the bottom and white (value 10) at the top. There are several colour solids and gray gradient in between.
Chroma measures the purity of a colour (saturation) with the lower chroma being less pure and appearing washed out, otherwise known as pastels.
Munsell colouring system is also referred to as the number theory. By identifying each colour with a universal number we can produce an accurate representation and of the colour pallet.

In 1810 Johann Wolfgang von Goethe; a German writer, artist and politician published a book titled Theory of Colours. He focused on the psychological aspect of how brain interpret colours and influence our emotions. Certain colours or colour combination create certain mood and feelings. He base this theory on the colour wheel designed by Isaac Newton and explained that there are ‘positive’ and ‘negative’ colours. Positive are also viewed as warm colours (yellow, orange) and negative are the cooler tones such as blue and purple.

He further elaborates of the different colour combination that could create certain atmosphere. Gentle – by mixing 2 negative colours we could potentially design a calm/ cold environment. For example a room filled with green and blue one would feel relaxed. Powerful – by mixing 2 positive colours we could potentially design a warm and lively environment. Yellow and orange creates an upbeat feeling. Radiant – by mixing a negative and positive tone.

In 1672 he published the theory on spectrum of light. In this experiment He passed a beam of sunlight to a glass prism, which refracted light to the opposite wall producing beautiful and vivid colours. He noticed that colours separating due to some hue refracted more than others eg: blue more so than red. His theory showed that light alone is responsible for colour. Colour is the result of light and not in the glass. He developed conceptual arrangements of colours in which artisan use as primary and secondary. The light that we see as white is a mixture of all the colours of the visible spectrum.

In about 300 BC a Greek philosopher Aristotle devoted much time understanding the theory of rainbow formation. His main idea is when ray of sunlight hit points in the raincloud they all deflective back at a fixed angle. As rays of the sun are parallel to each other they will deflect at the same angle at all points of the clouds. He used geometry to explain this theory ascertaining that if the ground is not in way we would see a full rainbow circle however with shadows in the way that is why we see an arch shape. There is no fixed point in the sky to locate a rainbow; its position is dependent on the observer’s location and the position of the sun. When we move our visual optic of the rainbow moves, with this in mind the myth of ‘pot of gold at the other side of the rainbow reminds a myth.

https://lindylublog.wordpress.com/2013/08/25/exhibition-critique-ian-strange/#respondSun, 25 Aug 2013 10:58:02 +0000http://lindylublog.wordpress.com/?p=128Continue reading →]]>The photography exhibition that I attended was held at the NGV on Flinders Lane Melbourne by an artist named Ian Strange. The shape of the gallery was a C shape with roughly 10 images printed to large format. Along with the images there were 4 projectors and old wood showcasing the timber of the houses. The first projector is located at the entrance inside the NGV, the second one on the wall in the middle of the room and the third one at the entrance of Flinders Lane. There are 2 headsets attached to this projector allowing viewers to watch and listen to the documentary and making of this project. There were lots of small tungsten lights shining down on the images.

There is a semi enclosed room, displaying more images on digital screen; the overall design of this exhibition is tidy, warm and inviting.

Suburban is a photographic exhibition of houses based in the suburbs in Ohio, United States of America. I was fortunate to have met the photographer and he explained that he started this project as growing up in small town Perth he felt there was a lack of opportunity, a need to conform and fit in. As an artist he did not fit in therefore throughout his childhood he felt there was a void in his life. These images are an expression of his feelings and emotions.

When he was old enough he moved to the United States to a small town and learn that there were others who grew up in the suburb feeling as trapped as he did. The GFC had a major impact on the locals in Ohio – their property which previously was worth $400K+ became worthless, sales did not exceed $15K. The tax and lending system is very different to how it is here in Australia, when property was repossessed the government demolish the houses and reclaimed the land. Strange applied to paint his artwork and torched these properties in the name of art. His application was accepted (as the houses were to be demolished anyway). His exhibition was a journey of this process.

The artist was able to convey his thoughts and ideas well through documentation at both entries of the exhibition. All the images carried the same theme; houses. This style was effective as the artist was able to retain the viewers focus and made them question and want to explore and interpret his idea. Each image was beautifully composed and photographed, they are all well thought out. The colours are vivid, the tonal range contrasting and the size of the print demanded attention. The images are extremely powerful. The auditory and documentary engaged the viewer and help them understand the story of locals in Ohio and the artist himself. Without this communication it may find it difficult to comprehend the emotion story behind the images.

I thoroughly enjoyed this exhibition. I love the images they are stunning. I appreciated the idea that the photographer was trying to convey, it’s interesting and to be able to communicate and inform the viewer is a gift.

Comment on the positive steps as well as the not so successful. Include your reflection of these images taken as well as your responses to those comments.

I have chosen 2 different media to publish my images. Facebook and Flickr.

The first image is a travel photograph that I took in Cambodia May 2013. When I published it to facebook I wrote a small script to describe the context of the image and to basically share my thoughts:

Cambodia – The slow birth of Peace. It’s difficult to envisage the pain and suffering during the Khmer Rouge revolution, one of the most radical and brutal restructurings of a society ever attempted. 36 years later the land is still undeveloped, the people still hungry and praying for better days.

Facebook: 169 people saw this post and there were 12 likes. Flickr: 8 view

The second image is a photo that I took for friends of a friend. Again I wrote a small script just to share some thoughts:

I really like this photo as it captures the essence of the bride and groom, very much in love.

Facebook: 720 views, 49 likes and 5 comments. Comments posted complimented the bride and how amazing she looks. I did not comment back. Flickr: 3 views.

Evaluation: Social media can be extremely effective depending on the social site and purposes of your image. For me facebook is more effective than flickr as I have dedicated a fair amount of time to build an audience of family and friends. I have not invested the same time to the flickr site therefore there were much less views.

The first image (Cambodia) received 169 views on facebook– from my photography and personal page. The second image (of the bride and groom) received 720 views, much more due to the tags that I have stamped. Not only has it been viewed through my family and friends but to the bride/ groom/ wedding planner and hair and makeup artist. And of course being a special milestone for the happy couple flattering comments were posted as a sign of approval. I signed up for deviant art for the purpose of this assignment, however like flickr I have not built an audience and therefore there were only limited views.
